Dynamics of a linear source epidemic system with diffusion and media impact
This paper studies an impact of media epidemic system with diffusion and linear source. We first derive the uniform bounds of solutions to impact on...

Renormalization of Higher Currents of the Sine-Gordon Model in pAQFT
In this paper, we show that the higher currents of the sine-Gordon model are super-renormalizable by power counting in the framework of pAQFT. First...

Numerical simulation of high-frequency induction welding in longitudinal welded tubes
In the present paper the high-frequency induction welding process is studied numerically. The mathematical model comprises a harmonic vector...

Epidemic modelling by birth-death processes with spatial scaling
In epidemic modeling, interpretation of compartment quantities, such as s , i , and r in relevant equations, is not always straightforward. Ambiguities...

Structural iterative rounding for generalized k-median problems
This paper considers approximation algorithms for generalized k -median problems. These problems can be informally described as k -median with a...

3D Tensor Renormalisation Group at High Temperatures
Building upon previous 2D studies, this research focuses on describing 3D tensor renormalisation group (RG) flows for lattice spin systems, such as...

On circuit diameter bounds via circuit imbalances
We study the circuit diameter of polyhedra, introduced by Borgwardt, Finhold, and Hemmecke (SIAM J. Discrete Math. 29 (1), 113–121 (2015)) as a...

Global attractor for the damped BBM equation in the sharp low regularity space
The long-term behavior of low regularity solutions to the damped BBM equation with a distribution force on the torus is studied. Since the energy...

Nonuniqueness of Weak Solutions to the Dissipative Aw–Rascle Model
We prove nonuniqueness of weak solutions to multi-dimensional generalisation of the Aw-Rascle model of vehicular traffic. Our generalisation includes...

Metrological Perspective of Ultrasonic Pulse Velocity Measurement Technique
The nondestructive testing of concrete structures by the measurement of Ultrasonic Pulse Velocity (UPV) is well known and widely used. Concrete is...

Monoidal strengthening and unique lifting in MIQCPs
Using the recently proposed maximal quadratic-free sets and the well-known monoidal strengthening procedure, we show how to improve intersection cuts...

Thermal oscillations and resonance in electron–phonon interaction process
A recent theoretical study (Xu in Proc R Soc A Math Phys Eng Sci 477:20200913, 2021) has derived conditions on the coefficients of Jeffreys-type...

Convergence of generalized MIT bag models to Dirac operators with zigzag boundary conditions
This work addresses the resolvent convergence of generalized MIT bag operators to Dirac operators with zigzag type boundary conditions. We prove that...

Moderate Deviations for Two-Time Scale Systems with Mixed Fractional Brownian Motion
This work focuses on moderate deviations for two-time scale systems with mixed fractional Brownian motion. Our proof uses the weak convergence method...
